Transportable air circulating and cooling assembly for use with a head covering

ABSTRACT

The present invention describes an air circulating and cooling assembly comprising a housing unit, adapted to quickly and easily secure onto a head covering, such as a hat, and an airflow distributor removably attached to the housing unit. The airflow distributor secures to the housing unit and has at least one vertically disposed aperture fluidly communicating air received from an air generator to the top of the user&#39;s head and at least one lateral disposed aperture fluidly communicating air received from the air generator along at least one side of said head covering. The airflow distributor is constructed and arranged to provide directional current flow of the air around the side and top of the head of the individual wearing the head covering wherein the current flow is expelled opposite from the head cover along the opposite side surface from where the airflow distributor is secured to the unit.

FIELD OF THE INVENTION

The present invention relates generally to an air circuiting and/orcooling assembly for use in combination with a head covering; moreparticularly, to a portable air circulating and cooling assembly for usein combination with a hard hat, the assembly designed for directing asupply of air to multiple sections of the hard hat, thereby evenlydistributing and circulating air therein and cooling down the internalhard hat environment.

BACKGROUND OF THE INVENTION

Numerous jobs require the use of a safety hard hat, such as constructionwork. In fact, given improved safety standard and regulatory laws, hardhats are required tools of many trades. Safety hats are typically madeof polyethylene plastic, making it lightweight, durable, easy to moldand non-conductive to electricity. Despite being lightweight, users areoften required to wear hard hats for extended time periods. For jobsperformed under high heat and/or excessive sunlight, continuous wearingof hard hats can be extremely uncomfortable for the wearer. Standardcomplaints about hard hats are that they are too hot. Removal of thehard hat can provide comfort. However, such relief is temporary asextended breaks are not usually tolerated. Modifications to the hard hathave been made to reduce excessive heat. For example, the S62 yellowhard hat made by Bullard® was designed with heat releasing vents forkeeping workers cool. The vented shell was designed to allow air to flowinside the hard hat, keeping the user cool and comfortable whileproviding quality protection.

Cooling mechanisms using fans to cool the internal area of a hat isknown in the art. For example, U.S. Pat. No. 4,893,356 describes acooling fan for a hard hat mounted on the surface of the hard hat. U.S.Pat. No. 7,143,451 is directed to a hat which is described as having anenclosed fan unit. The fan is described as being attached to the back ofthe hat and providing air flow over the head of the user. Because thecooling unit is encased within the hat, it is not portable. Lack ofportability is disadvantageous because, once the fan is broken, a newhat is required. Moreover, lack of portability results in increased costassociated with use of cooling features as the user is prevented fromusing a single cooling unit for different hats.

U.S. Pat. No. 7,114,194 is directed to a rear mounted plenum assemblydescribed as having a fan mounted therein. The fan may be located aroundthe back of a hard hat to direct air around the top of the head enclosedin the webbing. The assembly is built into the hard hat, and thereforesuffers from the same lack of portability issues as described above.

U.S. Patent Application 2007/0061946 is directed to a cooling unit for ahard hat that is described as being removable. The device contains ahousing unit that contains a fan, a power source, and a single tubularstructure that is coupled to the hard hat. The device is designed toprovide air flow using the single tubular structure so that air flow isdirected in a single direction. The '946 application fails to describedirected air flow in multiple directions.

Therefore, what is needed in the art is an air circulating and coolingassembly for use in combination with a head covering that minimizes airflow dissipation by directing the air flow to multiple locations withinthe head covering, thereby providing a circulating effect and enhancedcooling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now referring to the figures in general, and specifically in FIGS. 1-7,set forth is an illustrative embodiment of a removable air circulatingand cooling assembly for use in combination with a head covering. Theair circulating and cooling assembly 10 comprises a housing unit 12 andan airflow distributor 14 removably attached to the housing unit. Thehousing unit is adapted to easily and quickly install onto a headcovering, such as a hat. While the embodiment of the hat as describedherein is a safety hard hat typically used in the construction industry,any hat worn by an individual that is subject to excessive buildup ofheat could benefit from the present invention. Both the housing unit 12and an airflow distributor 14 may be made of the same material, such asa hard plastic. Alternatively, the unit 12 and an airflow distributor 14may be made of different materials such that the housing unit is made ofa hard, inflexible material, such as a plastic material, and the airflowdistributor 14 flexible material, such as a rubber material. In anotheralternative embodiment, housing unit 12 may be made of a combination ofmaterials such that at least one portion is made from a hard inflexibleplastic material (i.e. the internal section 18, see next paragraph fordescription) and at least one other portion, i.e. the portion thatextends into a hat such as the external section 16, see next paragraphfor a description), is made of a flexible rubber material.

The housing unit 12 has an external section 16 for positioning along theouter surface of the hard hat and an internal section 18 for positioningalong the internal surface of the hard hat. The external section 16 andthe internal section 18 have a bridge 20 therebetween. The bridge 20preferably forms a U-shaped structure, but such shape is not intended tobe limiting. The housing unit 12 is constructed and arranged to holdtherein necessary components to provide a functional device designed toprovide air circulation by evenly distributing air to the multiplesections of the hard hat simultaneously, thereby reducing the overalltemperature of the hard hat environment.

As an illustrative embodiment, the housing unit 12 comprises a frontcover 22, see FIGS. 8, 9, 10A and 10B, and a back cover 24, see FIGS.11A and 11B. The external surface 26 of the front cover 22 contains agrid-like cut out region 28 which allows for ambient air to be drawninto the housing unit 12. Additional cut outs 30 and 32, positionedalong the top 33 of the housing unit 12 are sized and shaped to receivefunctional control units such as power buttons or charging unit, asdescribed later. Along the left side 34 and right side 36 are firstportions 39 of a securing member, illustrated herein as a strap holder38. Although the strap holder is illustrated as being made of twoportions secured together to form the working unit, the strap holder 38can be made of a single unit attached thereto or integrally formed tothe housing unit 12. The strap holder 38 contains two L-shaped arms 40and 42 attached or integrally formed to the left side 34 or the rightside 36 of the housing unit 12. The L-shaped arms 40 and 42 extendtherefrom to form a first space 44 sized and shaped for receiving andholding a strap. The terminal ends 46 and 48 of the L-shaped arms 40 and42 are separated by a gap 50 which also functions to allow easyinsertion and removal of a strap.

Referring to FIG. 9, the internal surface 52 of the front cover 22 isillustrated. A plurality of recessed areas 54 with openings 56 arearranged to provide a means for securing functional components to theinternal surface 52. To provide a supply of airflow within the housingunit 12, an airflow generator 58 is secured to compartment 60, see FIG.10A, using a securing mechanism such as a screw 62 inserted into opening56. The airflow generator 58 may be a fan unit, such as a brushless fanor a blower. Preferably, the airflow generator 58 is a centrifugal fan64, see FIG. 10B, which is designed to move air into the unit 12 with anincrease in pressure to create an airflow supply through the use ofimpellers. While the centrifugal fan 64 is illustrated, other knownairflow generators or fan units known to one of skill in the art may beused. The centrifugal fan 64 contains a fan housing unit 66 having a fanwheel 68 composed of a plurality of fan blades 70 or ribs mounted abouta hub which is rotated by a driveshaft (not illustrated). Rotation ofthe fan blades draws air into the centrifugal fan 64 to the side, seearrows 72, turns 90 degrees and exits through an opening 74, see arrows76. As illustrated in FIG. 10A, the airflow generator 58 (shown in ahousing unit 77) is arranged within compartment 60 so as to directairflow generated into compartment 78. An opening 80 of the housing unit77 rests flush with dividing wall 82 as to prevent airflow generatedfrom being dissipated or directed to intended areas of the housing unit12. To generate a higher pressure ratio, i.e. the ratio of the dischargepressure over suction pressure, greater than 1.1, the fan may bereplaced by a blower.

Referring to FIGS. 11A and 11B, the internal surface 84 of the backcover 24 is illustrated. The back cover 24 is constructed and arrangedto secure to the front cover 22 to form the housing unit 12. Positionedalong the left side 86 and the right side 88 is the second half 90 ofthe securing member 38, comprising of two generally L-shaped arms 92 and94 attached or integrally formed to the left side 86 or the right side88 of the housing unit 12. The L-shaped arms 92 and 94 extendingtherefrom to form a first space 96 sized and shaped for receiving andholding a strap. The terminal ends 98 and 100 of the L-shaped arms 92and 94 are separated by a gap 102 which also functions to allow easyinsertion and removal of a strap or band. Securing of the front cover 22to the back cover 24 is accomplished by aligning the two sectionstogether so that posts 104 frictionally fit into recesses 104 located onthe generally L-shaped arms 40 and 42 of the front cover 22. Use ofscrews (not illustrated) inserted into and secured within openings 106(back cover 24) and openings 108 (front cover 22) may provide furthermeans of fastening. Additionally, the back cover contains a flange 110circumscribed about the perimeter which can be inserted within arecessed channel 112 located about the front cover 22 to provide airtight securing, thereby preventing airflow from escaping the housingunit 10 as well as preventing outside moisture from entering therein.

The internal surface 84 of the back cover 24 may be divided into severalcompartments, each holding functional components of the air circulatingand cooling assembly 10. For example, compartment 114 is sized andshaped to contain a removable battery 116, such as a 5V lithium battery.The removable battery 116 is electrically coupled to airflow generator58 to provide a source of electrical power to generate a continuoussupply of airflow. The internal surface 84 of the back cover 24 alsosupports a circuit board, such as a printed circuit board 118 viasupport structures 118 and 120. The printed circuit board 118 mayinclude, for example, a microcontroller (not illustrated) and associatedcircuitry (not illustrated). The microcontroller may be designed tointerface to switching circuitry that selectively closes and opens oneor more paths that allow the battery 116 to power on and off the airflowgenerator 58. The microcontroller also interfaces with one or more useroperated switches 124. The user operated switch 124 allows the user tocontrol the operation of the device, through on/off functionality (i.e.turning the airflow generator fan or blower on or off, or intermittentsuch that the fan or blower is automatically cycled on/off forpredetermined time periods) or airflow generator speed such asslow/normal/fast modes corresponding to the speed of the fan or blower.

To recharge the battery 116, the internal surface 84 of the back cover24 also supports a charge connector port, illustrated as a micro USBport 126. The printed circuit board 118 includes charging circuitry,operably coupled between the micro USB connector port 126 and thebattery 116 that operates to charge the battery using electrical powersignals supplied thereto by external power sources. Other chargeconnectors may be used as well, including a standard electrical outletplug. Additionally, the housing unit 12 may be adapted, i.e. to includea solar power panel and associated circuitry, to store and use solarpower. Preferably, the battery generates power for at least 8 hours andhas a charging capacity of over 1800 A. At the top 130 of the back cover24 are indicating lights 132 and 134. The lights 132 and 134 may bedifferent colors, i.e. one green light for indicating full batterycharge, one red for indicating low battery level. Additionally, one orboth may be designed to blink.

When sealed with the front cover 22, compartment 136 aligns withcompartment 76, allowing airflow to move from opening 80 of the airflowgenerator 58 thereto. A support panel 138 functions to support thebattery 116 and to provide sealing of compartment 136, therebypreventing fluid escaping into the housing unit 12. The front surface140 is designed to have an inset region so that once the front cover andback cover seal together a seal is formed around the opening 80.Compartment 136 contains airflow passageway 142, see FIG. 11A, whichterminates in opening 144 at the terminal end 146 of the internalsection 18, which may be divided into two channels 148 and 150, see FIG.11C. The airflow generated by the airflow generator 58 is directed tothe airflow passageway 142. The airflow generated is directionallyguided to opening 144 through the use of the bridge 20. The bridge 20 ispreferably a generally tubular, hollow structure constructed andarranged to help secure the removable air circulating and coolingassembly 10 to the hard hat, as described later.

Attached to the internal section 18 of the housing unit 12 is theremovable airflow distributor 14, see for example FIG. 1. The airflowdistributor 14 contains a front end 152, a back end 154, and a main body156 therebetween. The airflow distributor 14 is adapted to providedirectional air flow in a plurality of directions, thereby creatingcirculating air flow about the users head inserted within the hard hat.Since the airflow distributor 14 attaches to the housing unit 12, theair distributor provides an additional mechanism of securing theremovable air circulating and cooling assembly 10 to the hard hat.

The back end 154 is adapted to quickly and easily be attachable to andremovable (released) from the housing unit 12. Openings 158 and 160 aresized and shaped to receive tabs 162 and 164, see FIG. 11B and FIG. 7,thereby locking the two structures together so that the terminal end 146is positioned within the slotted opening 166, see FIG. 13. As describedabove, one of the main functions of the airflow distributor 14 is todirectionally distribute airflow generated to one or more locations. Tothat effect, the airflow distributor 14 may be hollow or partiallyhollow to allow for passage of air within. The airflow distributor 14contains at least one aperture chamber, and preferably a plurality ofaperture chambers 168, 170, 172, 174, and 176 for providing directedairflow delivery.

In contrast to prior art cooling systems, the present inventionminimizes air flow dissipation by directing the air flow to one or morelocations of the hard hat, thereby providing a circulating effect andenhanced cooling. Each of the aperture chambers 168, 170, 172, 174, and176 terminate in a vent or aperture. Preferably, the airflow distributor14 has at least one vertically disposed aperture and at least onelaterally disposed aperture. For example, at least one verticallydisposed aperture is formed by the aperture chamber 172 terminating inaperture 178. The at least one vertically disposed aperture is formed bychambers 168 and 170 terminating apertures 180 and 182 respectively.

Additionally, vertically disposed apertures are formed by chambers 174and 176 terminating in apertures 184 and 186 respectively. Asillustrated in FIG. 14, air flow, illustrated as arrows 190-198, isdirected through aperture chambers 168, 170, 172, 174, and 176 and outto the hard hat environment through apertures 178, 180, 182, 184 and186, thereby providing directional current flow of the air around theside and top of the head of the individual wearing the hard hat, whereinthe current flow is expelled opposite from hard hat along opposite sidesurface from the airflow distributor securement. The laterally disposedapertures may be staged or arranged in a plurality of arrangements. Forexample, the laterally disposed apertures may be placed on the leftside, right side, top side, bottom side, or combinations thereof. Thelaterally disposed apertures may be staged in a parallel manner so thatone aperture is directly above or below another aperture. Alternatively,the vertically disposed apertures may be arranged in a staggeredarrangement. Each aperture may include a curved surface to direct theairflow in an angled direction relative to the aperture. Alternatively,one or more aperture may contain a flap for directing the air flow at adirectional angle relative to the aperture.

As described previously, the circulating and cooling assembly 10 isdesigned for use in combination with a head covering. FIGS. 15-19illustrate the circulating and cooling assembly 10 in use with astandard hard hat typically used in the construction industry for safetypurposes. While the hard hat is illustrated as an exemplary headcovering, the air circulating assembly 10 may be secured to or otherwiseused with other hats, including but not limited to a football helmet.While attachment to certain hats, like the football helmet, can createdangerous conditions when secured to the helmet in use, the advantage ofthe air circulating assembly 10 in accordance with the present inventionis that it is easily transportable and easily securable to any hat. Assuch, in cases like a football helmet where any additional piececonnected to the helmet may be dangerous while playing, the presentinvention could be utilized when individuals are not directly involvedin live action. Rather, the air circulating assembly 10 may be attachedto a player's helmet during timeouts, while not playing on the field, orfor a quick cool down.

Referring to FIG. 15, the circulating and cooling assembly 10 is showncoupled to the back end 200 of a standard hard hat 202 using a strap 203secured to the strap holder 38. When activated, the circulating andcooling assembly 10 provides for airflow, see arrow 206, above theuser's head 204 as well as airflow, see arrows 208 and 210, to the sideof the user's head 204. As shown, the external section 16 is positionedalong the outer surface 212 of the hard hat, and the internal section 18is positioned along the internal surface 214, see FIG. 17. Referring toFIGS. 16 and 17, the standard hard hat 202 contains a rim 216 along theback end 200. The housing unit 12 is coupled to the hard hat 202 so thatthe rim 216 is inserted within and rests at a lipped portion 218, seeFIG. 6, of the housing unit 12. The terminal end 146 may include abeveled edge to provide ease of fit. Once in position, the airflowdistributor 14 is inserted so that openings 158 and 160 receive tabs 162and 164. The airflow distributor 14 extends up into the hard hat 202.Once activated, the airflow generator 58 provides a continuous stream ofairflow that is directed to the at least one vertically disposedaperture and the at least one laterally disposed aperture. Using atleast one vertical aperture and at least one lateral aperture provides aunique air flow pattern that delivers airflow to the top and sides ofthe back portion of the hard hat 202, see FIG. 18. As air moves from theback of the hard hat along the upper surface and the side surfaces,airflow is directed toward the front 220 of the hard hat 202 along thetop and sides of the user's head, see FIG. 19. Such pattern creates asystem in which air flow travels above the user's head as well as thesides as it is directed towards the front section 220 of the hard hat202. The airflow thus creates a circulating effect and minimizes patchesof cool spots created by devices that do not utilize lateral andvertical directed airflow.

The circulating and cooling assembly 10 is further designed to besecurable to a hard hat without interfering with additional structuralfeatures, such as head fastening straps 222 attached to the interiorsurface 214, see FIG. 17.
